Conduit i (Fig. l) m y'bring in receiving lines to box 2, say for signal as a bell in calling a subscriber. From this box 2 conduit 3 may extend to cradle having manually operable control means or dial ti which may be operable at such station when head set 6 is lifted from the cradle 4 and such dial t operated in the calling of central or some other remote station out of central or some other station under the system. Herein from such cradle or dial carrier t conduit l extends to housing 2. The conduit ll extends to terminals a, it (Figs. 2, 3) on insulation blockll carried by partition plate it, anchored to the housing 8 by screws it.

From the terminal t extends line it (Fig. 4) to contact it normally in switch closing position with contact it of line H to coil it, thence past condenser it to line it in completing circuit to the terminal it. ating the dial 6 to call remote station ringer box 2! having dial it has this station it effective in completing at once the ringing circuit between the terminals 9, ill, to have the coil it operate solenoid- 23 to withdraw terminal 2% from notch 25 in disk 26 fast to the shaft 21. On this shaft 21 there is located motor 28, preferably having a self-starting energy source. as a spring type motor, or an electric motor which is to an ex- This means that the one oper tent wound by the electric current as of certain clock types. Accordingly, on this release of the disk 2% by the solenoid plunger 23. the motor 28 is effective to start this shaft Zi and through cam 29 acting on roller 30 thrust switch carrying stem 3! to open the switch it, it. In so doing,

there is de-energizing of the coil it so that the plunger 23 rides against the disk 2% for single cycle operation of this disk 26, in that it effects a stop of such disk at once there is complete rotation, this stop being completed by this plunger 23 having its point 26 enter the recess 25.

In this starting operation, the cam 29 in its operation to open the switch it, it, simultaneously effects additional switching functions, in

that the contact it is closed with contact 32 communicating by lines 33, it, 35, with polarimng relay 35 having therewith condenser ti as a bypass to minimize contact arcing adjacent this polarizing relay 3t. The circuit for this relay, 36 is completed by line St to contact 39 with which, through the action of stem Qi, is brought contact is completing circuit by line ll with the line it. This means that the telephone'line circuit which released the disk 2% by the operation of the solenoid it, it, is effective on the polarized relay be. In energizing this relay, it is effective in operating switch it at such relay to line it-and coil tt froniwhich extends lines 3.55, tit, to contact ll, in cooperation with which is thrust contact it by the switch device it, thereby connecting line :39 which extends to terminal till. Adjacent the terminal Bill is terminal bi and frcm thae terminals in the housing b there extends conduit 52 (Fig. I): to energy source as battery 53 (Fig. 4). Accordingly, from this battery by the terminal 50 there extends line til to the line to. This completes the booster or energizing circuit for the accessory as in conjunction with the receiving station telephone and with a power beyond that normally in the line to such remote station. [This reserve power circuit from the line ht may conneot from the line fit by line 55 to coils 56 in series, and from thence by line bl to switch t8 as thrown by the coil to to complete circuit byv line 59 therefrom to the line it, thence to the.

contact ti as abutting the contact id and by line 49 therefrom to the terminal ht. Condenser M is a bypass between the lines it, lil, as to coils 58, herein shown as in series and effective to operate armature 60 against the action of spring 6! (Fig. 2)v and thrust plunger 62 through guide openings 63, 64,inacting on tape 65 (Fig. 4). This operation from the remote station is accordingly one transmitting the code impulses as coming to this accessory at the terminals 9, H], which code impulses as fortified by the battery 53 actuate the cutting punch 62 onthe tape 65 in marking such tape with notations 66 (Fig. 5) of the code identity.

The one having the accessory in the housing 8 at the receiving station may, through switch or manual control 61 (Figs. 1, 3, 4), out in or cut out the functioning of this code receiver and recorder device as for such remote station. With this device 6? in holding position, say as against rotary blade or fan 68, functioning of the motor 2% for rotating the shaft 21 and the cam 29 may not occur. However, as such shaft 2i may be driven from the motor 28, it is effective through speed reduction transmission 69 to operate drum 10 (Fig. 2) having traction friction facethereon. The tape 65 as of onion skin or thin paper may be held in contact with such face through the action of spring ll upon arm 12 and pivot bearing F3 for swinging roller it against the tape 55 and holding such against the feed roller ill. This tape is thus frictionally drawn from magazine reserve supply roll 15 having friction or resistance mounting hub 16 therefor to preclude excess unwinding at the pull operations of this feed roll 70. This strip of tape 65 from the roller 75 passes between die guides 63, 64, at which the spring 6| normally holds the armature 68 clear of the coils 56. This pair of coils 55 in their operation have a direct pull on this punch 52 in effecting the rapid code functioning or developing the marking 68 in the tape 65 as such tape is progressed by the feed roller it. Slack against untoward feeding or pulling of the tape 55 is obtained by the out-of-line small idler or guide 71. This strip of code-carrying tape 65 emerges from the housing 8 at port it, and as emerged therefrom may be torn by pulling against cutter 79. The single service or cycle operation of the motor 28 as determined by the plunger point 25 registering with the seat 25 permits the time interval for the calling station to effect the code setting or marking transmission even repetitively if desired. At the completion of the cycle independent of other conditions, the. device is automatically cut out for a repetition of a suc-' ceeding cycle of this functioning. Accordingly, the one at the station called, who has operated the selective cut-in ti, may thus have a record of the calls to which attention is to be given. However, if it be not desired to have these calls. come in, manual controller tl may be in the break position as to the motor 28 and thus allow the phone to function as normally in the matter of response and absence of response.

Herein with the controller Gl say to cut in an electric control, there may be a distinction in the busy call as to the one calling or non-answering, so that the remote station may thus be informed that a reminder in the way of code identification data'niay be supplied to such remote station as unanswering the call, so that as subsequent attention is given the remote station phone the return call may be placed.

In the carrying out of the invention herein, there is simplicity'with minimum of mechanical or moving parts required. There is a compact accessory in the housing 8 which readily functions as connected up with the increased energy source, as the battery 53. The dialing of the calling station is as normal, and when the sta- 7 tion does not answer such calling station may re-dial as a. signal for having such re-dialing not of the identity for such remote station as being called but say for the calling station or some station as to which it is desired to have the unanswering one respond. This means that the selection and full control of the code emanates from this one calling to the one failing to answer and is eflected by having such remote station dialing, as specially calling, perform the full sequence of code identification. The only mechanical parts required are the feed for the tape hereunder to receive the code and incidental thereto the switches functioning in determining the sequence. Fixed with the terminal or stem 2 is slide 80, which slide, as the stem 24 is in the notch 25, has its terminus Bl in'position to intercept the fan 63. In practice this means that at once the terminal 26 enters the notch 25, driving load is taken off the shaft 27 due to the fact that this slide terminus 8i intercepts the fan blade 68.
